This special television presentation was recorded as astrophysicist, cosmologist and New York Times bestselling author Neil deGrasse Tyson spoke at Bucknell University's Weis Center for the Performing Arts on Thursday, Jan. 30, 2014.

Tyson was host of the PBS show "NOVA ScienceNow" from 2006-11. He currently has a podcast, "StarTalk," and is working on a 21st century reboot of Carl Sagan's "Cosmos: A Personal Voyage" set to air on FOX.

Among Tyson's 10 books is his memoir, The Sky is Not the Limit: Adventures of an Urban Astrophysicist, New York Times bestseller Death By Black Hole and Other Cosmic Quandaries and The Pluto Files: The Rise and Fall of America's Favorite Planet, chronicling his experience at the center of the controversy over Pluto's planetary status.

Tyson was twice appointed by President Bush to serve on space industry and exploration commissions, and by NASA to serve on its prestigious Advisory Council. He is the recipient of eighteen honorary doctorates, as well as the NASA Distinguished Public Service Medal, the highest award given by NASA to a non-government citizen. In recognition of his contributions to the public appreciation of the cosmos, the International Astronomical Union officially named asteroid "13123 Tyson."

Tyson's presentation is part of the Bucknell Forum series "tech/no," which embraces technology and its perils and promises. The series aims to stir discussion about the pros and cons of technology, its benefits and damages, its legitimate promises and false panaceas, and its capacity to satisfy human need and desire even as it can bring risk and danger.
